The kit comes with customizable pieces—weapons and boobs—for both version of Fei-Yen, whether that's the TF-14+, which is named "Vivid Heart", or the TF-14 M+ version, which is named "Cinderella Heart".

This is kind of like what Sega did back in 2010, when it offered a "Fetish Unlock Code" for Xbox 360 game Cyber Troopers Virtual-On: Force that allowed players to make a similar adjustment—an adjustment I'm pretty sure isn't necessary for mecha.
